Title: Sensor arrangement
Inventor: BOWNASS DAVID CASSON
IPC: G01N21/55
Filed: 1996-11-29
Granted: 2002-08-20
Abstract: A substance sensor comprises an optical fibre having a core (1) and a cladding (2) having a lower refractive index. A layer (4) of cladding is left between a sensor material (3) and the core (1). The thickness (t) of the layer (4) is sufficiently small that the sensor material (3) lies within the evanescent wave which occurs within the cladding (2) when optical radiation is conducted through the core (1). The refractive index of the sensor material (3) varies in the presence of a substance to be sensed over a range which extends on either side of the refractive index of the cladding (2). When its refractive index is lower than that of the cladding the sensor material operates, as far as the radiation is concerned, similary to the cladding (2). Conversely, when its refractive index is higher than that of the cladding (2) the sensor material (3) couples out some of the radiation, reducing the transmissivity of the fibre. The sensor material may be polyethylene oxide, in which case the arrangement operates as a humidity sensor.

Abstract: Compensateur de var statique (SVC) polyphasé à condensateur actionné par thyristor, utilisant un transformateur (21) relié aux condensateurs du SVC (33, 43, 53) et configuré de façon que lorsque les condensateurs sont désactivés du circuit en séquence, la charge résiduelle sur les condensateurs est réduite par le transfert d'énergie entre le condensateur et un dispositif de dissipation d'énergie par l'intermédiaire du transformateur. Les primaires du transformateur (31, 51, 41) sont reliés aux bornes des condensateurs correspondants, alors que les secondaires (32, 52, 42) sont reliés en série suivant une configuration en delta. Des résistances d'amortissement (34, 44, 54) peuvent être reliées en série avec les primaires pour aider à dissiper l'énergie du condensateur. Le transformateur peut être saturable et peut être constitué de transformateurs individuels ou d'un transformateur polyphasé. Suivant une autre configuration applicable à un système triphasé, on utilise un transformateur monophasé dont le primaire est relié aux bornes de deux condensateurs reliés en série de deux des phases, alors que son secondaire est relié aux bornes du condensateur restant.

Abstract: Articles, such as components of an injection-molded multi-component product, are repositioned within a space, such as the space between mold parts, that is accessible for repositioning only during a series of periods, such as open-mold periods, that are separated by intervals of less accessibility for repositioning, such as closed-mold intervals by (a) moving a first article, such as a first component of a first multi-component product, from a first position within the space to outside of the space during a first such period; and (b) moving a second identical article, such as a first component of a secondmulti-component product, from outside of the space to a second position within the space during the first such period. Both the movement of the first article and the movement of the second article are by means of a common vehicle, such as a common robot arm. In another aspect, an article is repositioned by (a) moving the article from a first position within the space to outside of the space during a first such period; and (b) during a second such period after an interval of less accessibility that is subsequent to the first period, moving the article from outside of the space to a second position within the space. For injection molding with a stack mold, an article is repositioned from a first mold-cavity in a first space in a first portion of the stack mold to a second mold-cavity position in a second space in a second portion of the stack mold by (a) moving the article from the first position to outside of the first and second spaces during a period when the first space is accessible and the second space is inaccessible; and (b) moving the article from outside of the spaces to the second position when the second space is accessible and the first space is inaccessible.

Abstract: A bale shredder has a bale shredding chamber with a rotor at one side of the chamber. A conveyor extends from adjacent the rotor and slopes upwardly to a position adjacent the opposite side of the chamber. At the side of the chamber opposite the rotor, the shredder has a side gate with an upright position for round bale processing and a laterally extending position, aligned with the top rung of the conveyor for processing square bales. Above the rotor is a back plate that extends along the side of the bale chamber. The rotor is offset into the chamber from the back plate so that as a bale is processed, the material at a level above the rotor can pass over the rotor and be drawn down by the flails passing along its underside. The advance of the bale towards the rotor is controlled using an adjustable set of bale guards.

Abstract: An all-terrain-vehicle tire (10) has a tread (12) specifically designed for mud traction. The tread (12) has four circumferentially repeating rows (1, 2, 3, 4) of elongated lugs (40, 42), two shoulder rows (1, 2) and two central rows (3, 4). Adjacent the axially outer ends (45) of the lugs (42) of the central row (3, 4) is a shoulder block (44).  The tread (12) has soil discharge channels (60) extending axially between the lugs (40, 42). Each channel (60) is open in two locations (61, 62) to one or more axially aligned and circumferentially adjacent soil discharge channels (60). Preferably each location ( 61, 62) represents about 20 % of the axial arc width of a tread half. These locations (61, 62) permit mud to move freely from a forward channel (60) towards a rear channel (60) and enhances tread cleaning as the tire (10) rotates.

Abstract: The invention is directed at an additive for incorporation into a cementitious compound comprising Portland cement and water prior to the setting of the compound. The additive is comprised of a surface treated additive wherein the surfaces of the additive are treated with a substance which has a transient hydrophobic effect on the additive, which effect temporarily renders the additive more hydrophobic for a time period following the incorporation of the additive into the compound such that the water comprising the compound is less attracted to the additive during the placement of the compound and is thus available to provide workability to the compound, and such that the additive regains its natural properties following placement of the compound in order to permit the additive to participate with the compound during the curing of the compound. The invention is also directed at a process for preparing the additive and a process for preparing a cementitious compound comprised of the additive.

Abstract: The APC tumor suppressor protein binds to .beta.-catenin, a protein recently shown to interact with Tcf/Lef transcription factors. Here, the gene encoding a Tcf family member that is expressed in colonic epithelium (hTcf-4) was cloned and characterized. hTcf-4 transactivates transcription only when associated with .beta.-catenin. Nuclei of APC-/- colon carcinoma cells were found to contain a stable .beta.-catenin-hTCF-4 complex that was constitutively active, as measured by transcription of a Tcf reporter gene. Reintroduction of APC removed .beta.-catenin from hTcf4 and abrogated the transcriptional transactivation. Constitutive transcription of TCF target genes, caused by loss of APC function, may be a crucial event in the early transformation of colonic epithelium. It is also shown here that the products of mutant APC genes found in colorectal tumors are defective in regulating .beta.-catenin/Tcf-4 transcriptional activation. Furthermore, colorectal tumors with intact APC genes were shown to contain subtle activating mutations of .beta.-catenin that altered functionally significant phosphorylation sites. These results indicate that regulation of .beta.-catenin is critical to APC's tumor suppressive effect and that this regulation can be circumvented by mutations in either APC or .beta.-catenin.
